In a coal-fired power station, steam (H2O) enters the nozzle in a turbine at T1 = 800 K, P1 = 2 MPa at negligible velocity, and emerges at high velocity as a liquid–vapor mixture having quality x2 = 0.97 at P2 = 0.07 MPa. Assuming steady-state and negligible heat transfer, calculate the
Steam (H2O) enters the steam turbine in a nuclear power station at T1 = 800 K, P1 = 2 MPa at negligible velocity, and emerges at T2 = 370 K, P2 = 0.07 MPa. Assuming steady-state and neglecting heat transfer, and neglecting the potential and kinetic energy of the fluid at the inlet and
20 kg/s of water/steam enters the condenser in a central power station at T1 = 342 K with a quality of x1 = 0.98, and emerges as a saturated liquid at the same pressure (P2 = P1). Assuming steady-state, and neglecting the potential and kinetic energy of the fluid at the inlet and outlet of the

The throttling calorimeter is a device for determining the thermodynamic state of a fluid in vapor–liquid equilibrium. The procedure to estimate the vapor fraction of the fluid consists in bleeding off a small amount of the two-phase fluid, throttle it through a valve, and take the temperature
The cooling system for a small private jet airplane consists of the hardware shown here.High-pressure air from the aircraft engine compressor is fed to a small turbine at state 1 (temperature T1). The turbine extracts energy from the air, lowering the air temperature to state 2. This cold air is
A small solar engine is used for water pumping in a desert area. Water is the working fluid.Water enters the pump as saturated liquid at 50°C and is pumped up to 2 bar by a small centrifugal pump. The boiler evaporates the water at 2 bar, and saturated vapor at this pressure enters a small
At a tee junction in the piping of a chemical plant, 5 kg/s of methane enters on one side at P1 = 1 MPa, T1 = 400 K, and 1 kg/s of methane enters on the other as a saturated liquid at P2 = 1 MPa. The two streams are mixed and exit from the junction at P3 = 1 MPa. Assuming steady-state,
The inlet of the jet engine of a supersonic aircraft is a carefully shaped flow passage that takes in flow at very high speed ν1(relative to the engine) (section 1) and discharges the air at much lower velocity ν2 << ν1 and higher pressure (section 2) to the inlet of the compressor.
An impact press consists of a piston that is accelerated rapidly by pumping high pressure gas into the cylinder. The high-speed piston slams into the material to be flattened. Derive the equations needed to perform the design and analysis of this system according to the following suggested
A hydraulic turbine is fed with water from a reservoir whose free surface is at z1 = 22 m a.s.l. (above sea level). Water enters the turbine inlet pipe, flows through the turbine and its diffuser, and is discharged downstream of the dam at z2 = 14 m a.s.l.Calculate the average power that the
